Senate Majority Leader Mitch McConnell (R-Ky.) reportedly warned President Trump this week that declaring a national emergency to build his U.S.–Mexico border wall could create a rift in the GOP conference.

The Washington Post reported Friday that McConnell told Trump the Senate could pass a resolution disapproving the emergency declaration.

Republican sources familiar with the matter told the Post that the Senate leader and the president talked one-on-one Tuesday at the White House.

Sen. John Thune (R-S.D.), the No. 2 Senate Republican, said there is “not much appetite” for an emergency declaration; while Sen. John Cornyn (R-Texas), an advisor to McConnell, said lawmakers are trying to “dissuade” Trump and warned he could be challenged by Congress

There really is no way other than dealing with Democrats for him to get his wall. He’s gonna look like a complete dumbass (what else is new?) when the courts put a stop and he’s just left standing alone like the massive failure he is.
